linux – postfix多个IP SMTP横幅

概述我已经安装了postfix 2.11.3,我们的服务器上有多个IP地址,我们想要托管两个域,隔离并运行在自己的IP上. domain1 unix - - n - - smtp -o smtp_bind_address=1.1.1.1 -o smtp_helo_name=mail.abc.com -o syslog_na 我已经安装了postfix 2.11.3,我们的服务器上有多个IP地址,我们想要托管两个域,隔离并运行在自己的IP上.

domain1  unix -       -       n       -       -       smtp   -o smtp_bind_address=1.1.1.1   -o smtp_helo_name=mail.abc.com   -o syslog_name=postfix-mail.abc.comdomain2  unix -       -       n       -       -       smtp   -o smtp_bind_address=2.2.2.2   -o smtp_helo_name=mail.xyz.com   -o syslog_name=postfix-mail.xyz.com

以下传输器/ etc / postfix / sender_transport也在main.cf中定义：

@abc.com    domain1:@xyz.com    domain2:

重新启动postfix后,它停止侦听端口25：

[[email protected]]# telnet 1.1.1.1 25Trying 1.1.1.1...telnet: connect to address 1.1.1.1: Connection refused

但是,如果我在master.cf中使用以下行,它会在25上监听,如果我telnet,我可以看到横幅：

1.1.1.1:smtp inet  n - n - - smtpd -o myhostname=mail.abc.com 2.2.2.2:smtp inet  n - n - - smtpd -o myhostname=mail.xyz.com

但我想告诉我的邮件服务器,当你发送电子邮件时使用特定域名就像sender_transport一样

我做错了什么？

笔记：

我从master.cf中删除了以下行,并替换为上面的domain1和domain2：

smtp      inet  n       -       n       -       -       smtpd

解决方法 解决方案 – 需要Postfix 2.7或更高版本：

/etc/postfix/master.cf

#smtp      inet  n       -       n       -       -       smtpd127.0.0.1:smtp inet  n     -       n       -       -       smtpd      -o syslog_name=postfix-localhost      -o smtp_helo_name=localhost      -o smtp_bind_address=127.0.0.1      -o myhostname=localhost65.xxx.xxx.100:smtp inet  n     -       n       -       -       smtpd      -o syslog_name=postfix-mail.abc.com      -o smtp_helo_name=mail.abc.com      -o smtp_bind_address=65.xxx.xxx.100      -o myhostname=mail.abc.com65.xxx.xxx.200:smtp inet  n     -       n       -       -       smtpd      -o syslog_name=postfix-mail.xyz.com      -o smtp_helo_name=mail.zyx.com      -o smtp_bind_address=65.xxx.xxx.200      -o myhostname=mail.xyz.comabc-out  unix -       -       n       -       -       smtp   -o smtp_bind_address=65.xxx.xxx.100   -o smtp_helo_name=mail.abc.com   -o syslog_name=postfix-mail.abc.comxyz-out  unix -       -       n       -       -       smtp   -o smtp_bind_address=65.xxx.xxx.200   -o smtp_helo_name=mail.xyz.com   -o syslog_name=postfix-mail.xyz.com

/etc/postfix/main.cf中

sender_dependent_default_transport_maps = hash:/etc/postfix/sender_transport

/等/后缀/ sender_transport

# Use source IP - [email protected]                abc-out:@example.com            abc-out:# Use source IP - 65.xxx.xxx.200 @xyz.com                xyz-out:

运行命令以生成哈希数据库

postmap hash:/etc/postfix/sender_transport

重新启动/重新加载后缀

service postfix reload

瞧！看到它使用65.xxx.xxx.200 IP地址发送电子邮件..
